Transporting the bathtubs, which each weigh a whopping 10,000 kg, was no easy feat.

"Transporting such fragile and valuable pieces of crystal was something we took very seriously. Everything was checked before being packed and transported and experts carried out detailed inspections at every stage," Mr Yachmenev said.

"The pieces were packed by skilled handlers who loaded them into specially constructed crates that had a material lining to absorb shock and prevent moisture. They were transported by sea in specially designed temperature controlled containers."

The glimmering centrepieces were crafted by Florence-based company Baldi Home Jewels.

"Baldi is a company that has carved out a niche for itself creating luxury items for those who appreciate the finer things in life so their ethos really resonated with us.

"We are delighted with the end result and are excited that the residents of XXII Carat will be among the first in the world to bathe in these exquisitely designed tubs and enjoy the truly unique, magical and luxurious experience," Mr Yachmanev said.

The group has already sold 50 per cent of the development.

With million-dollar bathtubs, we can only imagine what a night in one of these luxury pads might cost. So what sort of person can afford a night here, you ask?

"Typically, our buyers are over 45 years old. They are successful businessmen and women, owners or directors of large companies, politicians or high profile sports personalities. They also tend to have big families," Mr Yachmanev said.
